It should be noted that the material of the seal ring 27 is not limitedthereto, for example, the seal ring 27 can be made of a foam cottonmaterial. It should further be noted that, in the actual productionprocess, compared with the seal ring 27 made of a silica gel material,the seal ring 27 made of a foam cotton material may require a greaterwidth and larger space. Moreover, as the diameter of the through hole221 of the display screen 22 gets smaller, a sealing space may begradually decreased, and space for receiving the seal ring 27 may bemore limited. Compared with the seal ring 27 made of a foam cottonmaterial, the seal ring 27 made of a silica gel material, may occupyless space to prevent dust and light leakage.

In some embodiments, a thickness of the seal ring 27 may be greater thanor equal to a thickness of the optical adhesive 211, such that the sealring 27 may have a light-shielding function, that is, the seal ring 27,surrounding the through hole 221, can prevent light rays of the displayscreen 22 from being transmitted to the through hole 221. Herein, theterm “thickness” used here refers to a length of the component (such asthe seal ring 27, the optical adhesive 211, and the like) in a directionfrom the light-transmission cover plate 21 to the display screen 22.

In some embodiments, the seal ring 27 may be a circular ring structure.More specifically, a transmission hole may be defined in a middleposition of the seal ring 27; the transmission hole may be configured totransmit signals. It should be noted that the shape of the seal ring 27is not limited thereto, for example, the shape of the seal ring 27 maybe a hollow rectangular structure.

In some embodiments, a width of the seal ring 27 from a free end to aconnecting end can be gradually increased. It can be understood that theconnecting end of the seal ring 27 is fixed on the light-transmissioncover plate 21, and the free end of the seal ring 27 may be located at atop position of the seal ring 27 after the seal ring 27 is fixed on thelight-transmission cover plate 21, the top position of the seal ring 27can be referred to the top 271 shown in FIG. 17. It should be noted thatthe structure of the seal ring 27 is not limited thereto. Herein, theconnecting end of the seal ring 27 may be configured to connected to thelight-transmission cover plate 21, the free end may be opposite to theconnecting end.

In some embodiments, the seal ring 27 can be merely fixed on thelight-transmission cover plate 21 and configured to be separated fromthe display screen 22. The seal ring 27 may be not in contact with thedisplay screen 22, that is, a gap can be formed between the seal ring 27and the display screen 22, and the gap may be a part of the through hole221.
